MINE-CAR. 4

I To -all may 05mm.-

Be it; known that I, MAn'r1n 'S. RUNsvoLD,

a citizen ofthellnited States, residing at Bisbee, in; .thecounty of Cochise and State of Arizona, have invented certainfnew and Mine- 1Cars,of which useful Improvements in the following is a specification.

Thisinyention relates generally to oars,

andrgparticularly to carsfori use in 'mining z the invention is The primary ;ob'ect of p to providea car '0 I this character which is capable of'beingquicklyv and easily dumped and reset,.-and;xwhich has; its body so arranged as to; becapable of being dumped iniya number of different directions.

;A.further. object of the invention is to provide a dumpjcar of the character set forth which canbe dumped without in any .way disturbing the truck, and which involves :anifimproved; means for locking the bodyagainstrotary or dumping movement.

.A StIll furtherobject of' the invention is to'providea dump car whichhas its body constructed z-in1suchmanner as to :enable a number of such cars to be coupledtogether to form a train, and the'cars'are'connected in such manner iascto obviate the, opportunityxof the same to become derailed when the trainis rounding sharp curves.

With these objects in view, together with others which will appear as the description proceedsgthe invention :resides in the novel formation, combination, and arrangement offiparts, all as'will be described more fully hereinafter,illustrated inzthe drawings, and particularly pointedaout in the. claims.

Figure 111s a top plan view of a dump car constructed in accordance with this invention,-' :1 r w 7 Fig.2 is afront elevation of-the said car, isE-a longitudinal sectional view taken through :the car body :and the, truck therefor," I

"Referring .now particularly to the drawings,-6"rep'resents the truck upon; which the body of the dump car 'is mounted, and-this truckincludes the supporting axles. or

bolsters 7, upon which the wheels 8 are mounted. The 'car body indicated gener ally' at 9,1 i rotatably mounted upon the. truck at. the center thereof, and is also ca-f pable ofiro'cking Vertically.

The truck 6'is provided with an upstand plate being adaptedfto'support'the body of the vehicle. ",The' plate 11 isprovided with r a pair; of diametrically oppositeupstanding ears" 12, which are adapted to cotiperate with th'e d'epending ears formed at the ex: trer'nities ofa laterally disposed strap member 13 on the bottoni'of the car body; a pin 14 being employedto hold the; ears 12 and 13 in proper assembled relation.- This constructlon permits of the body beiligreadily rocked vertically so as to dump. 3

The forward and reari laterally disposed plates at the ends of the truck 6 are inclined upwardly. and inwardly and each is provided adjacent its ends with upstanding s QP members 15 the' sa'id stops between them forming .achannel '16. .Each of the" saidendfplates is provided with a centrally arranged upstanding-"pin'17, and the said plates are held rigidlyin' the truck frame by str'ap members or braces 18 connected at. f

their inner ends tothebolsters or axles 7.

The car .body 9-has depending from one corresponding with: the inclination of the end, plate of thetruck. Thisfoot is of a width equal to the distance between the upstanding portions 15 upon. the truck plate, so as to snugly fit between the same. The foot is also provided with a central aperture asshown particularlyin Fig. 3 of the drawings, the said aperture being adapted to receive the pin 17 inone of the opposing truck plates. The foot isso arranged that '85 a I end thereof. a. foot19, the lowerend of which is inclined upwardly and inwardly when it is within the recess .or channel 16,

the car will beheld in proper horizontal po sition, and when it is desired to rotate the car-body, .one end thereof may be depressed, whereuponthe' foot 19 will be raised from engagement with the pin 17 and out' of the 7 channel 16. As soon as the sides of the 7 foot have cleared the sto 1 the Said y y ero atedi g p V 7 Associated with a car body and truck of this character is an improved locking means, the same in the present instance comprising an elongated bar or rod rotatably mountr ed in suitable keepers 21 upon the bottom of the car body, and extends longitudinally and centrally thereof. One end of the rod projects beyond the corresponding edge of the car body 9, and is bentupwardly to provide a catch portion 21 adapted to engage with the lower edge ogtthe endgate 22 of thecar bodyv to hold thesame against being opened. The opposite end of the bar or rod 20 extends downwardly and inwardly to provide a latch portion 23 for engagement withinthe loops formed by the strap members 1 8 at each end of theitru'ck. When the bar visin the position shown in Fig. 3, the door-22 will be held against being opened, and the portion 23 will be engaged within the loop 18 to preventthe body from being rocked vertically. WVhen it isdesired'to rotate or dump. the car,.the rod 20 may be rotated in such direction as will cause the portion 22 to be retracted from engagement within the loop 18, whereupon the body 9 is free to be rocked vert1cally. It will also be obvious that this rocking movement of the bar 20 will cause thecatch portion 21 to be disengaged fromthe end gate 22. w

The mean"s for c i ntrollingv the rocking movement of the rod 20 comprises lever 25, pivoted as at 26 to one'end of the car, and a link'27 connects the lower end of the lever with the depending member 23 of the bar 20. A link 28 isarranged on the car ,body to engage over the end ofthe'lever 25 to hold the latter against rocking movement. It is preferred that; the lever 25 be located so as to be capable of being operated without "entering between the cars. I a

As a brace and additional support for the car body, a pro ection 30 extends outwardly and upwardly from one end of the fifth wheel plate 11, and this projection straddles thebar 20 and is adapted at its extremity to engagejth bottom of the car 9.. A kingbolt 31 connects the fifth wheel plates. 3

In order that several of the cars thus constructedwhen hooked together to form a train may freely move laterally relative to each other, as is necessary in rounding sharp curves, the ends of each car are rounded as shown. It will beobserved that the chains, hooks and eyes are arranged upon the car bodies intermediate the longitudinal edges thereof, so that pull will be exerted upon the bodies at the center thereof. This manner of coupling the cars obviates the possibility of overturning of the same when roundingsharp curves. It is also obvious. by rounding the ends of the cars the I hands ofthe operator maybe insertedbetween the cars to effect the coupling of'the and may being rocked upon their pivots to dumping position.

Chains 33 and hooks 34. may be used in coupling the cars, and each carmay be provided at one end with an ey'e'35 t6 receive the hooks ofthe next adjacent car.

From the foregoing it is obvious that I tremely siniple construction and which is capable of being readily operated. of the cars of a train may be dumped, one at;

a time or all tegethe'r withoiit'abuttiijg'the next adjacent carand withoutdafiger cr- Iil derailing the trucks; It is also app that "the car body ma be'quick ly i'eversed, be locked firmly against oscillating or rotary movement.

WVhilethe pres e t is a'di'sclosure'of what is believed tote the preferred "embedimfent have provided a mine earwhieh is 'o f ex,- 7

of the invention, it isjto be understeod that the invention is not limited thereto, but that various changes in the minor details ofcom struction, proportion, and arrangement of parts may be resorted to if 'desiredwithoilt departing from the spirit of theinvention as' defined by the appendedclaims.
